ATOMIZER.

Application filed July 31,

To all whom it may concern:

Be it known that I, HERMAN C. Blam MER, a citizen of the United States, and resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an. Improvement in Atomizers, of which the following is a specification.

The object of my invention is to provide a construction of atomizer, especially'useful in treatment of textile fabrics, which will insure a most thorough vaporization of theliquid with a given minimum blast pressure, whereby a uniform moist atmosphere may be obtained throughout the chamber through which the fabric is passed.

Moreparticularly my object is to provide the atomizersindividually .with nozzles respectively for blast pressure and liquid, arranged at an angle to each other and relatively adjustable in a common frame, to bring the orificesinto different adjusted positions relatively to each other; .and preferably, so that each nozzle may be adjusted axially in the frame to and from the axial line of the other nozzle.

In practice, thesenozzles are usually employed in batteries arranged within a coinmon tank having means for maintaining a constant water level to insure a definite and constant lift for the water to the atomizer nozzle, and the atomizers are sustained by horizontal blast or pressure pipes upon which they are mounted, the construction providing fixed. blast nozzles upon which is mounted a vertically adjustable frame in which is mounted. the water nozzle having one end extending down below the. water level in the tank and the other or nozzle endarranged horizontally in alinement with a vertical plane through the axial line of the blaster pressure. nozzle and preferably adjustable to or from the axial line of said nozzle. My invention also consists of improve ments hereinafter described whereby the above objects andresults are attained, said improvements comprising certain organization and combination of partswhich are fully described hereinafter and more particularly defined in the claims. I

Referring to the drawings: Fig. 1 is a plan view of a portion of a tank with my improved atomizers applied thereto; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a sectional elevation of the nozzle struc- 1919. Serial No. 314,583

Thesepipes 2 may be supplied with compressed air or other pressure mediuinfas steam if desired), by p pes l5 and 16,,connecting with pressure pipe l3, and.pressure from which may be shut off or controlled bysuitablevalves 14, of wh ch there may be a separate valve for each pipe 2. 12 represents a sidewall of the textile machine injwh ich' theitank 9 is located. From theupper part of the pipes 2 there extend the vertical blast or pressure nozzle pipes .3 upon which are respectively mounted the remaining parts of the at omizers proper.-

Referring to Fig. 3, it will be seen that the blast nozzle ,3 is conicalat the top having a small orifice centrally arranged and is also screw threaded upon its outer surface at 26. Sleeved upon the upright blast nozzle 3 is a right-angled frame 4 having a hole 18 which fits the nozzle-and a transverse slot 22 in which an adjusting wheel 25 is received, said wheel having a screw threaded hole and screwed upon. the nozzle 3 i In this manner the frame 1 may be adjusted to or from the nozzle end .6 of nozzle 3. By turning the wheel 25 to the left, the frame 4 is moved upward toward the nozzle end 6 and when turned to the right, the frame is moved downward. The other or upright arm of the frame4 isprovided with a horizontal hole17 and a transverse slot 21 of similar construction to the parts 18 and 22, but said sets of parts of the two arms of the frame are at right angles to each other. 5 is a horizontal water nozzlehavinga conical end and nozzle aperture, corresponding to blast nozzle 3; and similarly, itis provided with a screw threaded outer. surface 2 1. This horizontal water nozzleis inserted through the horizontal hole 17 of theframe 4 and has its supply or suction end 7v extended down into the water 8 inthe tank 9. The nozzle 5 is also provided with an adjusting wheel 23 fitting the slot 21 in the frame 4 Specification of Letters'Patent. Pate t d J l 25', 1 2 i and screwed upon the screw threads 24- of the nozzle, whereby a rotation to theleft advertically and horizontally with respect to the nozzle 3 to provide the proper relation of the two orifices of the nozzles, whereby the best results may be obtained. If the air blast from nozzle 3 is relatively low in pressure, it is desirable to lower the nozzle 5 so that not only is the lift required to be less but the effectiveness of the blast from nozzle 3 to atomize the water is increased, this latter being assured by the horizontal adjustment also of nozzle 5.

To prevent any relative shifting of the nozzles after having been adjusted, 1 provide the frame a with a slot 19 extending throughout its body from hole 17 to holelS and also with a transverse clamping screw 20 by which the two parts, on either side of the slot, may be drawn together to cause the hole portions 17 and 18 to grip and hold the nozzles 3 and 5 respectively. p

The essential feature of my invention resides'in the capacity for relative adjustment of the two nozzles 23 and 5, whereby the desired mist or vapor may be secured with any given blast pressure, whether it be compressed air or steam. Nhile the atomizers are ordinarily used to vaporize water, it is manifest that they may be employed to vaporize chemical solutions for various purposes.

In use with textile machinery the atomizers are arranged along the lengths of pipe 2 in any numbers found necessary, as will be understood by reference to Fig. 1.

It will now be apparent that I have deviseda novel and useful construction which embodies the features of advantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent, is
